X^2 + 16x + 61 = 0
x^2 + 16x = -61
x^2 + 16x + 64 = -61 + 64
(x + 8)^2 = 3
x + 8 = (+-) sqrt 3
x = -8 (+-) sqrt 3
x = -8 + sqrt 3...and x = -8 - sqrt 3 <== ur solutions
Answer:
The correct answer is option A.
Step-by-step explanation:
Number of circles = 64
Number of square = 96
Number of triangles = 48
Factor of 64, 96 and 48;



Factors do these numbers have in common are:
64 = 2 × 2 × 2 × 2 × 2 × 2
96= 2 × 2 × 2 × 2 × 2 × 3
48= 2 × 2 × 2 × 2 × 3
Common factors = 2 × 2 × 2 × 2 =16
This is a relatively simple half life calculation.
To go from 6 to 3 grams, 1622 years is required.
3 to 1.5 grams another 1622 years is required.
So, it undergoes exactly 2 half-lives or 3,244 years.

Answer:
see the procedure
Step-by-step explanation:
The situation could be
Alice needs to divide 1/4 pound of meat into three equal parts. What is the weight of each part?
so
Divide 1/4 by 3

The weight of each part is
